UPPER SLIDE MOUNTING FOR MIILTIPLE-SPINDLE LATHES.

Specification of Letters Patent.

Patented Au n'24, 1915.

Application filed January 21, 1915. Serial No. 3,432.

To all whom it may concern I Be it known that I, WILHELM 'SCHMITT, a

7 subject of the German Emperor, residing at Cologne-Klettenberg;Germany, have invented new and useful Improvements in Upper-SlideMountings for Multiple-Spindle Lathes, of which the following is aspecification.

This invention has special reference to improvements in latheconstruction and more particularly to an improved upperslide mountingfor multiple spindle lathes.

With multiple spindle lathes, that is lathes commonly known as of thistype hav ing a plurality or several spindles, crossslides are used forturning the work or stock and usually there are as many spindles on thelathe as there are slides. Of these slides, those next to the frame ofthe lathe are usually carried or supported in a comparatively rigidmanner, while hitherto, this was not the case with the upper-slide,

the latter being generally fixed on the turret supportbut in such amanner to be constantly vibrated so that the use thereof wasconsiderably impaired and when subjected to hard work, it was at timesimpossible to operate or work said upper-slides at all.

It is an object of the present invention to overcome these difficultiesand for this purpose, the upper-slides are solely carried on the frameon both sides, in lieu of being fixed self-carrying on the turretsupport, whereby any lever operation produced by the self-carrying.construction is prevented, so that the upper-slide can be used foreffective working.

Referring to the accompanying drawings: Figure l is a longitudinalsection of a lathe equipped in accordance with the invention. Fig. 2 isa sectional view taken on the line A-A of Fig. 1, with a front view ofthe slide.

As illustrated, on the frame a is fixed the turret support I)which'carries the intermittingly turning spindle-turret or turret.

a. This turret is provided with. four spindles d e f and g for carryingthe work or stock to be operated on and in order to turn the work or.stock,

four radially movable slides h 2', k and Z are provided. Of theseslides, the slides h and Z lying horizontally next to the frame of thelathe, are fixed to the latter, while the slides 71, is are heldtogether in a carrying-piece m which is provided with prolongations n, F.0 which are in the form of oppositely extending supports. 'Theprolongations n. and .0 are fixed or held motionless on one side of theturret support b and on the other side are similarly fixed to thebearing p which is in turn fixed on the frame a. In this manner. theupper-slides 2' and k are firmly fixed on both sides with re spect tothe longitudinal dimensions of the lathe orframe thereof, by theprolongations/n and 0, constituting a longitudinal brace or anchoringmember for the carrying-piece m through which it is engaged, and thusfor the upper-slides i and 7c Although theupper-slides i and is areillustrated as mounted on a single carrying-piece m, so far as thepresent invention is concerned in its broad aspect, it

does not matter whether the slides i and I 7c are supported orpositioned to ride on separate carrying-pieces m whereby each of them isprovided with a separate connecting rod or prolongation n and 0,

,or if they are arranged in groups.

The invention can be used quite as well for any number of spindles andslides and thus is adapted for varying types of lathes.

What I claim is:

1. In an upper-slide mounting for multiple spindle lathes, thecombination with a lathe frame, a turret support and a turret carriedthereby; of spindles carried by the turret, slide bearings carried bythe frame,

additional slide bearings and means bracing the latter slide bearings oneither side of the latter to the support and frame, respectively.

2. In an upper-slide mounting for multiple spindle lathes, thecombination with a lathe frame, a turret support fixed thereon, a turretcarried thereby to be intermittingly turned, a plurality of spindlescarried by work carrying spindles, a plurality of slides, acarrying-piece, upper-slides carried by said carrying-piece, a bearingat one end of the frame, androds projecting in opposite dlrectlonslongitudinally of the frame from slides.

4. In an upper-slide mounting for multiplespindle lathes, thecombinationwith a i frame, a turret support carried thereby,.a

turret rotatablyv carried by said support, a

plurality of spindles for carrying work supported by said turret, and 1aplurality of slides for turning the work to be acted on,

'Z said slides comprising an upper series and a .Gopies or this patentmay be obtained for five cents eachQ-by addressing the f Commissioner ofPatents; Washington, D. G. 1 a T r 7 1 lower series, the lower seriesbeing positioned adjacent to and supported on the frame;

of a carrying-pieceto which 'theuppervslides are held, a bearing at oneend of the "frame opposing the turretsupport and extensions projectingin opposite directions from said carrying-piece to firmly fix the sameand the slides carried thereby to the frame said extensions engagingsaid bearings and the turret support respectively.
